What are the characteristics of the music and dance "Dian Ting Le Ge" in Jin Dynasty?

In the Jin Dynasty, there were music and dances at large banquets in the court, which were called "Dianting Music Songs". Its form is also a banquet, singing and dancing. The banquet is in wheels, and performances are performed between wheels, including singing, civil and military "two dances", dance performance (no dancing), song performance (no singing) and so on. In addition, the Jin people are completely open to highly artistic Han Song and dance performances. Learning and spreading advanced Chinese culture is a remarkable feature of Jin people's cultural mentality. In Jinshantun Tomb in Yichun, Heilongjiang Province, a musical and dancing relief stone building was unearthed, which was in the shape of octahedral white marble and engraved with eight musicians and dancers. One of the legs is half open and half crouched, his arms are flat and his forearm is raised, his head and trunk are slightly tilted to the right, and his left foot seems to be stepping on the joint, which is vivid and unique. The other seven music kings in Shilou all hold musical instruments that spread in the Central Plains, such as Zou, He and Gu. The music and dance image of the Han nationality in the tomb of the Jin people fully embodies the tolerance of the Jin people to other national cultures. The boy dancing figurines in the golden tomb in Jiaozuo, Henan Province convey the temperament of the golden man.
